Thank you for that.
Regarding the roof, which I understand to be your main question, I will turn to Ezio DiMillo to give you more details about the technical specifications of that roof, but I do wish to mention that we have come to the conclusion that this was the best option after an evaluation of several other options, including a copper roof, for example. The decision to proceed with a glazed roof has been supported at many levels of approval, and relating to the incremental cost, it has proven to be minimal.
Ezio, please, can I ask you to address this?
